Get std::function from template parameters

I am trying to implement some kind of task-class that will be done after some time. Currently I have to implement class, say for example TimeoutTask (needed for the bigger task). In it's body I want to get std::function from template parameters and this function I will call after some extra logic. The problem is that I can't properly "create" this function. But I can call it directly. Where is the problem? (I haven't use templates too much before, just simple ones)

class TimeoutTask
{
public:
    template <class Class, class Method, class... arguments>
    TimeoutTask(int timeout, Class *obj, Method f, arguments&&... args)
    {
        // here I get error: error C2059: syntax error : '<tag>::*'
        std::function<std::result_of<decltype(obj)(Class)>::type(arguments...)> 
            task(Class::*Method, obj, std::bind(std::forward<arguments>(args)...));

        // here will be some extra logic
        // and after this extra logic I want to call 'task' somehow

        // but I can call it just by this way:
        (obj->*f)(args...);     
    }
};

And code for creation of this "task":

SomeClass sc;
TimeoutTask testTask(1000, &sc, &SomeClass::someMethod, 101);
